Is DNA a single strand of nucleotides?
No, DNA is a double-stranded molecule composed of nucleotides. Each strand has a specific sequence of four different nucleotides: adenine, thymine, cytosine, and guanine. These two strands are connected by hydrogen bonds to form the double helix structure of DNA.
If there are 1200 nucleotides in DNA strand how may codons will be in mRNA strand?
There will be 400 codons in the mRNA strand since each codon consists of three nucleotides.
What enzyme links DNA nucleotides to a growing daughter strand?
DNA polymerase is the enzyme that links DNA nucleotides to a growing daughter strand during DNA replication. It catalyzes the formation of phosphodiester bonds between adjacent nucleotides on the new DNA strand.
Is strand of nucleotides in the RNA or DNA?
A strand of nucleotides can be found in both RNA and DNA. RNA is typically single-stranded, while DNA is double-stranded. Both molecules consist of nucleotides that contain a sugar, a phosphate group, and a nitrogenous base.
Why do dideoxy nucleotides cause the DNA strand to stop elongating?
Dideoxy nucleotides lack a hydroxyl group at the 3' carbon, which is crucial for the formation of phosphodiester bonds during DNA synthesis. Without this hydroxyl group, the dideoxy nucleotides cannot form a bond with the next nucleotide in the growing DNA strand, leading to termination of strand elongation.
During DNA replication a primer attaches to a template strand of DNA and begins a new strand. After the primer has attached an enzyme extends the new strand of DNA by adding nucleotides that correspon?
The enzyme responsible for extending the new DNA strand by adding nucleotides is DNA polymerase. It reads the template strand and adds complementary nucleotides to form a new DNA strand. DNA polymerase can only add nucleotides in the 5' to 3' direction.

What enzyme links DNA nucleotides to a growing daughter strand?
DNA polymerase is the enzyme that links DNA nucleotides to a growing daughter strand during DNA replication. It catalyzes the formation of phosphodiester bonds between adjacent nucleotides on the new DNA strand.
What type of bond is between nucleotides?
In producing a strand of DNA the nucleotides combine to form phosphodiester bonds.
What attaches free nucleotides to the growing DNA strand?
DNA polymerase attaches free nucleotides to the growing DNA strand during DNA replication. DNA polymerase catalyzes the formation of phosphodiester bonds between the nucleotides, incorporating them into the new strand complementing the template DNA.
What is one role that triphosphate deoxyribonucleotides play in a cell?
Triphosphate deoxyribonucleotides form hydrogen bonds with their complements in a DNA parent strand during transcription of the leading strand of DNA. Example Adenine nucleotides bind to thymine nucleotides Guanine nucleotides bind to Cytosine nucleotides
What is the name of the enzyme that adds nucleotides to dna?
The enzyme that adds nucleotides to DNA is called DNA polymerase. It plays a crucial role in DNA replication by adding complementary nucleotides to the existing DNA strand during the synthesis of a new DNA strand.
How many nucleotides would it take to construct the mRNA coding strand of the β-subunit of the hemoglobin A molecule?
441 nucleotides
What is the enzyme that uses one strand of DNA as a template to assemble nucleotides into a strand of RNA?
RNA polymerase is the enzyme that uses one strand of DNA as a template to assemble nucleotides into a strand of RNA during transcription.
How many strands of nucleotides does a molecule of RNA contain?
A molecule of RNA contains one strand of nucleotides.
What does it mean to say DNA polymerase reads a template strand to make the complementary strand?
DNA polymerase is an enzyme that catalyzes the process of replicating DNA molecules. When it "reads" a template strand, it uses the sequence of nucleotides on the template strand as a guide to synthesize a complementary strand by adding complementary nucleotides one by one. This process ensures accurate replication of genetic information during cell division.
